New Feature: MARC Import

This is not a bobcat

MARC is the library standard for bibliographic records. We’ve always parsed MARC records behind the scenes, when members searched one of our 700 library sources, or our Overcat collection. A few years ago, we introduced the ability export your LibraryThing collections as MARC records, even if your records didn’t start out in MARC.

Now, we’re adding the last piece: MARC importing, for all the small but professionally-cataloged libraries that use LibraryThing.

How it works. To use MARC import, you’ll need to have your library data in a .marc file format. Depending on how large a file you’ve got, the import process may take a few minutes. The good news is, you’ll receive a notification from LibraryThing once it’s ready. From there, you’ll be able to review your import options—just like you would with any other import—and select the collections, tags, etc. you’d like to apply to the items you’re importing.

What is MARC? MARC stands for Machine-Readable Cataloging. It represents a set of digital formats for describing items held by libraries: books, maps, CDs/DVDs, etc. You name it, if it’s in a library, MARC can handle it. Libraries the world over use MARC to standardize their item records in such a way that information about different types of items can all be fed into (and retrieved from) cataloging systems uniformly.

MARC fields are denoted by numerical tags, that indicate what type of information is contained in that field. For example, the title of a given work is always in field 245.

Don’t Upload The New York Public Library! This is for small—or, better the tiny—libraries that use MARC records and LibraryThing. Uploads are capped at 10,000 records total, so don’t try to upload 100,000 records. “Regular” libraries, big and small, should check out LibraryThing for Libraries, a remarkable suite of catalog enhancements.
